DOUCHE.

Application Afiled February 19, 1920; Serial No. 359,990. Renewed April 18, 1922. Serial No. 555,228:

T o all whom t may concern:

Be it known that I, WILLIAM FRASER, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful improvements in Douches, of which the following is a speciication.

The present invention relates to improvements in douches, that is to say to devices for irrigating and cleaning certain parts of the body, such as for instance the mouth cavity, nasal passages, etc.

rlhe main obj ect of the invention is to provide la device of this type, whereby a medicated liquid is supplied' under pressure, preferably derived from a water faucet, to the parts to be cleaned.

Another object of the invention is to produce a douche of the character mentioned which is simple in construction, efficient in operation and one which may be convenient ly handled. y

With these and other objects in view,

which will more fully appear as the nature of the invention is better understood, the same consists in the combination, arrangement and construction of parts hereinafter described, pointed out inthe appended claim and illustrated in the accompanying draw-l ings, it being understood that many changes may be made in the size and proportion of the several parts and details of construction within the scope of the appended claim, without departing from the spiritor sacriicing any of the advantages of the invention.

One of the many possible. embodiments of the invention is illustrated in the accompanying drawings, in which :-v

'Figure 1 is a side elevation.l partly in section, of a douche constructed in accordance with the present invention; and Fig. 2 is a section taken on line 2--2 of Fig. 1.

In the drawings, the numeral 1() indicates a chambered body, mounted upon a handle 11. The chamber 12 of the body 10 is providedwith an inlet opening 13, in communication with a tube 14, the latter leadingV through the handle 11 and having a nipple 15, with which is engaged one 'end of a,pref erably, exible hose 16, the lother end of which is adapted to be connected with a water faucet. The chamber 12 is furthermore provided with a discharge opening 17, to which is connected a nozzle 18, the free end of which is provided with a plurality of perforations 19. This nozzle is adapted to be inserted into the cavity to be irrigated and cleaned.

yUpon the chambered body 10 is mounted a receptacle 20, Ihaving a filling opening 21, that 1s normally closed by a cap 22. The/re,` ceptacle communicates with the ichamber 12, the communication being controlled by a valve 23, for instance a poppet valve,l upon thestem of which is coiled a spring 24e", tendingv to hold the valve upon its seatf lThe outer end of the valve; is provided with a head 25, against which bears a shiftable member 26,' that is mounted on guides 27 onV the body 10. rFhis shiftableimember is provided with a fin er piece 28,1 projecting below the chambere body 10. l

In use, a medicated liquid, for instance an antiseptic solution, is placed into the receptacle 20 and .the hose 16 attached to a water faucet. The nozzle 19 is inserted into the cavity to be cleaned, and the faucet turned to open position. 'The operator forces the finger piece 28 toward the handle 11, whereby the valve 23 is unSeated and a quantity of medicated liquid fiows into the chamber,.where it mingles with the water passing through the same and is carried under pressure into the cavity to be cleaned.

lThe quantity of medicated liquid flowing into the chamber is within the control of the operator, it dependin entirely upon the time interval during which the valve is kept from'its seat. When the finger piece 28 is released, the spring 24 seats the valve, there by stopping the flow of medicated liquid into the chamber 12.

The nozzle 18 is detachable from the chambered body and may be replaced by others of varying sizes, according to the requirements. l

What I claim is:-

In a device of the character described, the combination Vwith a chambered body having an inlet opening and a discharge opening, a handle supporting saidcharnbered ,body a tube passing throughsald handle communicating with said inlet opening, a nozzle attached to Said chambered body communicating with said discharge opening, a closed receptacle mounted upon and adapted to communicate with the chamber in said body, a valve for ontrolling the rcominimication between said chamber and said receptacle, and means projecting below said chambered body and mounted adjacent said handle for operating said valve.

Signed at New York, in the county of New York and State of New York, this 29th day of December, 1919.
